Title: Belt for continuously variable transmission
Inventor: WAKUI HIROSHI
IPC: F16G5/16
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To enhance the durability of an assembly of metal rings by preventing a metal element from inclination relative to the ring assembly. SOLUTION: A belt for continuously variable transmission is arranged so as to satisfy the condition L/t<=FL/2FV, where FV represents a tangential friction force which the pulley abutting surface 37 of a metal element 32 receives from a pulley, L is the radial distance from the acting point 45 of the tangential friction force to a rocking edge 40 positioned outside in radial direction of the acting point 45, FL is the load directed inward in radial direction which the metal element 32 receives from an assembly 31 of metal rings, and (t) is the thickness of the metal element 32.  Even if a moment of FV×L acts on the metal element 32 owing to the friction force FV, the moment FV×L is canceled with a moment FL×(t/2) generated by the load FL with which the ring assembly 31 presses the edge (a) of a ring slot 35, and it is possible to prevent the metal element 32 from inclining.

Title: Information recording medium
Inventor: KOBAYASHI TADASHI
IPC: G11B7/24
Filed: 1988-09-30
Abstract: PURPOSE:To enable fast erasing of records in a phase-transition type recording medium by providing crystallized thin films having higher m.p. than that of a recording layer on one or both sides of the recording layer and thereby raising the crystallization rate of the recording layer. CONSTITUTION:The recording layer 2 and the crystallized thin film 3 are successively deposited on a substrate 1. Crystals in the crystallized film 3 give seeds of crystallization of the recording layer 2 in the interface of the recording layer and the crystallized film 3 and promote generation of crystal seeds. Since the crystallized film 3 has higher m.p. than that of the recording layer 2, it does not melt or change into an amorphous state by irradiation of laser light. Thereby, the crystallization rate of the recording layer 2 becomes fast, so that records can be erased fast. The same effect can be obtained by providing the crystallized films 3 on the both sides of the layer 2.

Abstract: PURPOSE:To sensitively control a temperature of a penetration factor of molecular beam intensity by making a thermal shield plate approach close to an outer periphery of a heater as well as by making a space between an inner face of the heater and an outer periphery of a cell extremely small. CONSTITUTION:A heater 14 is composed of heater lines wound with small interval spirally on the outer periphery of a cell 3, and as its winding pitch in a radiation port 3a region is made smaller than that in a center portion 3b region and exothermic density is made large, a temperature T1 of the radiation port portion 3a is made higher than a temperature T2 of the center portion 3b in heating. A thermal shield plate 15 is the same one in which, for instance, plural tantalum plates Ta are piled up with a space as a -thermal shield plate 5, and coats the outer periphery adjoining each other on the outer periphery of the heater 14. As a space between the inner face of the heater 14 and the outer periphery of the cell 3 becomes much smaller than that of the former, and besides, the thermal shield plate 15 adjoins to the outer periphery of the heater 14, efficienct heating of a material M through the cell 3 of the heater 14 is remarkably improved than that of a heater 4.

Abstract: PURPOSE:To softly start charging and to improve charging efficiency by providing a duty variably drive circuit for varying the duty of an input pulse in response to the number of input charging pulses. CONSTITUTION:A duty variably driving circuit 1 for varying a duty in response to the number of input charging pulses in such a manner that a resistor of a discharge circuit is removed, is provided.

IPC: F16F15/02
Filed: 1996-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a dynamic vibration absorber which is attached to beams or sleepers to provide dynamic vibration absorbing action, and a dynamic vibration absorbing method using its dynamic vibration absorber. SOLUTION: The design of a dynamic vibration absorber 2 in which elastic members 10 and 12 support a heavy weight section 8 creates resonance frequencies decided by the spring constant of the elastic members 10 and 12, and the weight of heavy weight member 8. Therefore, by fixing mounting sections 4 and 6 of this dynamic vibration absorber 2 to a building, specifically to two beams (or joists) 24 of a wooden building respectively in a way that it bridges both beams or (joists 24), the shock from the floor resonates the dynamic vibration absorber 2, thereby absorbing it dynamically, thus the shock as well as the transfer to other members are immediately reduced. This works for the reduction of particularly a heavy weight repercussive sound among repercussive sounds.
